基于PERT技术的建设项目进度控制研究——以上海国际金融中心项目为例

Research on Project Schedule Control Based on PERT Technology:Taking the Shanghai International Financial Center Project as an Example

突破以往PERT模型中工期必须符合正态分布的传统思路,提出工期符合概率分布P的假设。在此基础上,以上海国际金融中心项目进度控制为例,分解调整项目工序的逻辑关系,将三时法运用到PERT方法中,计算得出对定目标的实现概率,并调整优化得到可实现性强的项目工期排布,为应用较多新工艺的复杂项目进度控制提供参考。

This paper breaks through the traditional idea that the time limit in the PERT model must conform to the normal distribution,and puts forward the hypothesis that the time limit conforms to the probability distribution P. On this basis,takes the project schedule control of Shanghai international financial center as an example,firstly decomposes and adjusts the logical relationship of the project process,applies the three-time method to the PERT method,calculates and obtains the probability of achieving the given goal,then adjusts and optimizes,and finally gains the time schedule of the project with strong realizability,provides reference for the progress control of complex projects with more new technologies.
